Answer:
3 x^2 - x + -1
Step-by-step explanation:
Simplify the following:
-(4 x - 2 x^2 - 3) + x^2 + 3 x - 4
Factor -1 out of -2 x^2 + 4 x - 3:
--(2 x^2 - 4 x + 3) + x^2 + 3 x - 4
(-1)^2 = 1:
2 x^2 - 4 x + 3 + x^2 + 3 x - 4
Grouping like terms, 2 x^2 + x^2 + 3 x - 4 x - 4 + 3 = (x^2 + 2 x^2) + (3 x - 4 x) + (-4 + 3):
(x^2 + 2 x^2) + (3 x - 4 x) + (-4 + 3)
x^2 + 2 x^2 = 3 x^2:
3 x^2 + (3 x - 4 x) + (-4 + 3)
3 x - 4 x = -x:
3 x^2 + -x + (-4 + 3)
3 - 4 = -1:
Answer: 3 x^2 - x + -1

Answer:
25? to be honest i really dont know :/
Step-by-step explanation:
um pemdas says 5x5 is 25 so 5+(25)-5/5 then you do -5/5 is -1 and thats 5+(25)-5 then you add 5 to 25 and thats 30 and minus 5 is 25
The total should be 287.59. You add the numbers (127.12+94.50+65.97) and it should equal to that.
That would not be right because 4 times 3 equals 12 and -6 times 3 equals -18.
